In the suggestions in linked article, there were many of the socialistic countries' policies, but the difference is that in those, either taxes are high and more or less everyone pays their share, or income is negotiated in net salary, so (high) deductions aren't even visible. In Thailand, other than some middle class, barely anyone pays taxes, so to get such a scheme going, the rich and the poor would have to be taxed. Putting more burden on middle class will break it and cause even a larger gap. But just think of who is in power. Are they ever going to go out on their limb to tax themselves to finance this? In your dreams.
